Every time I was debugging my pages I found myself searching around for this little chunk of code to display PHP errors. So, I put in the book so it was always nearby. Since people still search google endlessly, I thought I would provide it here as well. If you wish to see all the PHP errors and warnings in your script, include the following bit of code:
error_reporting(E_ALL); ini_set('display_errors', '1');
Now, continue to beat your head against your keyboard while you continue to hunt down your missing semicolon or closing parenthesis.
